Configurable Status Code in Templates Rendered From Routes

Contributed by Dale Nash
in #41414.

In Symfony applications controllers render templates most of the times.
However, you can also render templates from routes config for simple cases
where creating a controller would be unnecessary.
In Symfony 5.4 we're improving this feature to allow you define the HTTP status
code of the response that contains the rendered template (to override the
default 200 status applied to these responses):

# config/routes.yaml
upload_started:
path: /upload_started.html
controller: Symfony\Bundle\FrameworkBundle\Controller\TemplateController
defaults:
template: 'file_upload/started.html.twig'
statusCode: 202 # HTTP Status = Accepted

New innerText() Method in DomCrawler

Contributed by Bilge
in #42338.

The Symfony DomCrawler component eases DOM navigation for HTML and XML
documents. In Symfony 5.4 we're improving it with a new innerText() method.
It's similar to text() but it only returns the text that is the direct
descendant of the current node, excluding any child nodes:

$text = $crawler->filterXPath('//body/p')->innerText();
// if content is Foo Bar
// innerText() returns 'Foo' and text() returns 'Foo Bar'

Recursive .gitignore Support in Finder

Contributed by Julien Falque
in #43150
and #43837.

The Symfony Finder component allows you to apply the .gitignore rules of
the directory where you are searching. This way you don't need to repeatedly
exclude some files or directories from the search:

// if .gitignore file exists in the directory, its contents
// are parsed and applied to the file/dir search
$finder->ignoreVCSIgnored(true);

In Symfony 5.4 we've improved this feature to better align with Git's default
behavior. When enabling this feature, the Finder component will use the
.gitignore files of all subdirectories traversed during the search. Also, the
rules of subdirectories always override the parent directories rules.

New Command to Debug Environment Variables

Contributed by Christopher Hertel
in #42580.

Configuration based on environment variables is increasingly popular in
Symfony applications. Given that many different files can define and override
those env vars, in Symfony 5.4 we've added a new debug:dotenv command to help
you debug the value of all your env vars and which .env files were checked:
